3. INTRODUCTION
 Now a days the use of vehicles are the part of life
 Vehicle reduces the distance and saves time of busy human
life, still it has great drawback that is inevitable
 Road mishaps occurs due to carelessness, condition of roads,
technological fault etc.
 In 2014 around 4.8 lakh road accident occurred in which
4.5lakh people get injured and 1.4 lakh people die every year
due to road accident in India
 Compared to day time risk of accident is three times at night
time

5. NEED OF ADAPTIVE LIGHTENING
SYSTEM
• Conventional front
lightning system is
static
• low beam or high
beam
• Illumination at
corner is not
possible while
taking a curve

6. NEED OF ADAPTIVE LIGHTENING
SYSTEM(Cont…)
• AFS control headlight
during vehicle’s turning
from driver’s point of view
• AFS consist of real time
sensor mounted on steering
shaft
• Improves visibility
• With better illumination,
stress and fatigue of driver
reduces

7. DEVELOPED SYSTEM ARCHITECTURE
7

8. WORKING
• Output from rotary potentiometer
and multi turn preset is supplied
to logic IC
• Multi turn preset is used to set
benchmark
• Logic IC used as comparator and
works only if incoming value is
more than or equal to benchmark
value
• Signal from logic IC is amplified
using transistor
• Output from transistor is fed to a
12V DC relay through diodes
• Output from relay to LED

10. HARDWARE IMPLEMENTATION

11. FUTURE DEVELOPMENT
• Common rubber based
platform for holding LED
can be developed
• Microcontroller chip can be
used to compact the design
• Dedicated steering angle
sensor can used instead of
potentiometer

12. ADVANTAGES
 Cost effective solution for the problem of accidents occurring
night time
 It can be easily mounted on cars
 Enhances existing functionality of the headlight system
 Increases visibility of the driver at curves
 Increased safety for drivers and pedestrians
12

13. DISADVANTAGES
 Continuous power supply for sensor circuit
 Dislocation of LED may happen due to vibration
 Use of potentiometer as angle sensor is not reliable due to its
error causing tendency with time
 Present prototype is needs to be modified to make it
compatible with all power steering based vehicles

14. CONCLUSION
 AFS serves as a reliable and efficient system for efficient
driving at sharp turn
 System is inexpensive, simple and dependable assembly
 Simple comparator based circuit is used ,which uses very
simple logic and makes it most economical to use
 AFS ensures degree of safety in vehicle and assistance to
driver
